MOLDING-MACHINE.

My invention relates to apparatus for packing sand or similar materialabout patterns in molds, and has for one of its objectsto provide aconstruction of this character embodying a rotatable packing memberwhich is mounted for operation in a novel manner.

Other objects will be set forth as my description progresses, and thosefeatures of construction, arrangements and combinations of parts onwhich I desire protection, succinctly defined inmy-anneXed claims.

Referring to the accompanying drawing, 1

wherein likenumerals of reference indicate like parts throughout: Figure1 is a top plan. Fig. 2 is an end elevation with parts broken away, andFig. 3 is a vertical longitudinal section.

Referring to the drawing by numerals of reference 1 indicates thepacking roll or cylinder, the same being journaled in a frame 2 which issuspended by flexible connection 3, consisting of a short length ofchain, from a carrier 4 which is provided with roller 5 engaged on atrack 6. Frame 2 is provided with forwardly projecting side extensions2' to which is secured a handle 7, which latter can be grasped by theoperator to advance and retract the roll 1, carrier at moving on track 6to permit of this, as is apparent. Flexible connection 3 is providedwith end hooks 3 which are i normally engaged in eyes of the carrier 4and frame 2, as clearly shown in Fig. 2. Through the provision offlexible connection3, the pressing roll is permitted to have a slightupward movementwhen brought into engagement with the sand, and the rollat such time will have its full weight imposed on such material. Track 6constitutes a horizontal extension of a vertical support 8 which latteris mounted for vertical and rotary adjustment in a guide 9.

In the present embodiment of my invention, I aim to provide aconstruction which is portable, the same comprising a truck 10 havingsupporting wheels 11 and Specification of Letters Patent.

conveniently provided with stand 12 for the mold 13. Guide 9 is fixed totruck 10 and spaced from stand 12 longitudinally of the truck. Thesupport 8 extends through guide 9 and the body or bed of truck 10 andhas its lower end engaged 011 a bearing 14, consisting of a rollerjournaled in the free end of an arm 15, fixed to a horizontal rock shaft16, j ournaled in depending bearings of truck 10. Rock shaft 16isprovided with an operating handle or lever 17, through the medium ofwhich said shaft and arm thereof can be swung to effect verticaladjustment of support 8. For holding lever 17 in its adjusted position,I provide the same with a latch 18, adapted for engagement with a rack19 fixed to a truck 10. Latch 18 is connected by a link 20 to anoperating han die 21.

-In the operation of my apparatus, track 6 is first lowered to enableroll 1 being advanced to pack the sand in drag or bottom section of mold13, following which and after the cope is applied, track 6 is elevated,and roll 1 again advanced.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent of the United States of America, is

1. In apparatus of the character described, means for supporting a mold,a

packing roll for operation on a mold supported on said means, a frame inwhich said roll is journaled, an elevated track, a carrier on saidtrack, and a connection secured to said carrier and to said frame, saidconnection being flexible whereby the roll can move upwardlyindependently of the carrier through resistance of the material beingpressed during a packing operation and be suspended thereby when it isremoved from the mold.

2. In apparatus of the character described, means for supporting a mold,a packing roll for operation on a mold supported on. said means, anelevated track, a carrier on said track, and a flexible connect ingmeans depending from said carrier and supporting said roll, whereby thelatter is free of said carrier for relative upward movement during apressing operation.

3. In apparatus of the character described, means for supporting a mold,a roll for packing the sand in said mold, a

track, means supporting said roll from said track for movement acrossthe face of the mold, and means carrying said track for verticaladjustment.

4;.In apparatus of the character described, a track, means supportingsaid track for vertical and rotary adjustment, a carrier supported formovement on said track, a packing roll suspended from said carrier, andmeans for supporting a mold for operation thereon by said roll.

5. In apparatus of the character described, a truck, a horizontal track,means supporting said track for vertical and rotary adjustment, means onsaid truck beneath said track for supporting the mold, and a sandpacking roll suspended from said track for movement over and crosswiseof said last named means.

6. In apparatus of the character de scribed, a vertical support, meanssupporting said support for vertical and rotary adjustments, a trackcarried by and projecting from the side of said support, a packing roll,means carrying said roll mounted on said track, means for supporting amold, and means for vertically adjusting said vertical support.

I11 PP ratus ofthe character de scribed, a substantially horizontaltrack, a vertically disposed support, a truck, means on said truckrotatably receiving said support, a packing roll, means on said trackcarrying said roll, a lever having the lower end of said verticalsupport seated thereon,

packing roll for operation on a'mold supported on said means, anelevated substan tially horizontally disposed track, means supportingsaid track for horizontal adjustment With respectto said first means, acarrier on said track, and a connection secured to said carrier forsupporting said roll, said connection being flexible whereby the rollcan move upwardly independently of the carrier during a packingoperation.
